Patent number: 9195485Abstract: A wireless network device includes a wireless network port, first and second virtual machines, and a processor. While executing the first virtual machine, the processor stores, in a third queue, data to be processed by the first virtual machine and the first virtual machine maintains, in a first queue, a copy of the data stored in the third queue. While executing the second virtual machine, the processor stores, in the third queue, data to be processed by the second virtual machine and the second virtual machine maintains, in a second queue, a copy of the data stored in the third queue. Upon resuming execution, the first virtual machine transfers, to the third queue, the copy of the data maintained in the first queue. Upon resuming execution, the second virtual machine transfers, to the third queue, the copy of the data maintained in the second queue.Type: GrantFiled: November 11, 2013Date of Patent: November 24, 2015Assignee: Marvell International Ltd.Inventors: James Chieh-Tsung Chen, Chuong Vu, Chor-Teck Law, Binh Quoc Tran, Jiaqi Shen, Brian Bosso

Patent number: 5790436Abstract: A system and method of simulating operation of an integrated circuit. First, circuit characteristics of circuit components are measured, and a set of circuit simulation model parameters are generated for each measured circuit component. Then, the operation of predefined circuit primitives is simulated using each of the generated sets of circuit simulation model parameters. The circuit primitives include the measured circuit components. The simulated operations are then analyzed to select ones of the simulated operations that are worst, best and nominal with respect to a specified circuit performance parameter and to extract model parameters corresponding to the worst case, best case and nominal case sets of circuit simulation model parameters from the generated sets of circuit simulation model parameters. Each extracted set of circuit simulation model parameters comprises one of the generated sets of circuit simulation model parameters.Type: GrantFiled: November 3, 1997Date of Patent: August 4, 1998Assignee: BTA Technology, Inc.Inventors: James Chieh-Tsung Chen, Zhihong Liu, Chenming Hu, Ping Keung Ko
